mother's father

My mother was born on May 8, 1932, in a Salvation Army Home, in Spokane, Washington.Her first name is Shirley, middle name is Laverne. She was given the last name of Rhinehart at birth, although we have no idea why.Her mother's name was Mae Marie Talbert.She was 16 and not married.Her father is listed as Luther Sarrett, occupation is listed as soldier.The birth certificate says he is from Virginia, and that he was 27 years old at the time.She has never met him or anyone in her family.She just recently obtained a birth-certificate and found out his name.Her mother later married and my mother always went by that surname, McLain, until she married.I would appreciate any help I can get.We know nothing of her heritage on the paternal side. -thank you, Keri Dfietrich
